GSM and CDMA (Contd.)

My video of Tips for Buying a Used CDMA (Verizon, Sprint) Cell Phone. So pretty much this video says a couple tips when buying a CDMA phone which are phones that don't use SIM Cards. GSM phones are phones that use SIM Card (T-Mobile, AT&T/Cingular) CDMA (Verizon, Sprint). So when buying best is to check ESN/MEID/HEX which are numbers and letters on the back of the phone behind the battery ranging from 8 - 17 letters and digits. What you want to do is call 611 on your phone and chose to talk with a representative (your name & last 4 digits of SS will be mostly required). Then give them the ESN/MEID/HEX and the will check it and let you know. After check of most primary functions are fully working on the phone. Also if you don't want to call or go online, just go to your local Verizon Wireless or Sprint store to let them check and activate right then and there. Account holder must be present though. You can also activate the phone by calling 611 also. Takes approx 5 - 15 Min. Or log onto My Verizon and you can also activate through there would take less time and be a less hassle. Sprint and other CDMA carriers not sure of but mostly similar. If you have any questions or comments please feel free to let me know. Thanks For Viewing!

Can you use CDMA phone on GSM network? (Verizon/Sprint/T-Mobile/AT&T) In this video, we take a close look how CDMA phones differ from GSM phones and whether you can use CDMA phones on GSM network (and vice versa). Verizon and Sprint = CDMA T-Mobile and AT&T = GSM You can't use CDMA phones on GSM networks (unless they are world phones with SIM card support). T-Mobile and AT&T use different 3G frequencies so there's a problem there too. For Globe-trotters, your best bet is AT&T as they are on 1900Mhz for 3G/HSPA+, meaning you can swap out SIM cards and get full voice/3G/4G data anywhere else in the world you go. ++++++++++++++++++++++++++++++++++++++++++++++++ I use Canon 7D for recording most of my YouTube videos, for my setup, see here: www.youtube.com ++++++++++++++++++++++++++++++++++++++++++++++++ Want to contact me?

This video demonstrates the various cases and skins we tested with the CDMA Samsung Galaxy Nexus and the OEM Extended Battery installed onto it. In a nutshell - skins and flexible cases should work just fine, while rigid style covers shouldn't work. Special hybrid and layered cases have to be individually tested to see if it works or not. Keep in mind we can't test everything out there, and more stuff will come out in the future for the phone; so just use common sense and our guideline to give you a better perspective.

We go hands on with the 4.3 inch display of the ZTE warp. It's specs are impressive, but does it live up to it's claims and is it worth it for you to upgrade? My impressions so far are mostly positive and it's definitely an upgrade. First time Android users will be impressed as this phone performs as well as many upper end contract phones, and Android veterans will appreciate it fast response and ample storage. Available now and contract-free for $200 and it runs on Sprint's CDMA 3G network.

DroidModderX.com Twitter @DroidModderX Rom Dev @Romanbb Grab this Rom here forum.aokp.co Support threads for AOKP at Rootzwiki: rootzwiki.com AOKP is one of the leading Roms available today! It started out as a Kang of CyanogenMod9 hence the name Android Open Kang Project. Where Cyanogen Mod has really slowed down on inovation and new features, Team Kang has really picked up the ball and ran with it. This Rom is quickly becoming the new standard! The main feature here is Rom control. Rom control has enough features to keep you busy for an hour or more. Not to mention it is running on the faux kernel allowing for overclocking up to 1480mHz. This Rom is officially supported on 26 devices and has also been unofficially ported to several other devices. Chances are if you have an android device you can run this super awesome version of ICS!

The kittenz in California have chewed upz my internetz, Phil is back online. The Verizon iPhone, as predicted, was announced yesterday. This model of the iPhone 4 is CDMA capable and will run on Verizon's 3G network. Although Verizon has there 4G LTE network, we won't be seeing that on this iPhone. The iPhone 4 you see with Verizon is almost exact to the GSM counterpart. The only difference, so far, is a new black separator line up above the silent switch. The model show at todays event was running iOS 4.2.5. One of the new features of 4.2.5 was Personal Hotspot, which allows you to use your iPhone as a WiFi network(like tethering), except you can link up to 5 devices. So far, Apple/AT&T has only allowed 1 device to be tethered via Bluetooth or USB. With Verizon's Personal Hotspot you can connect with WiFi, Bluetooth, and USB. This of course costs an extra $20 for AT&T subscribers, and curious to see what Verizon will come up with, plan-wise, No information has been shared on the data plans, but will be announced at a further date. That further date should be somewhere close to February 3rd, when pre-orders start for existing Verizon members, or February 10th when the CDMA iPhone is available for purchase to the public. Whether the CDMA iPhone 4 will be available in different colors, such as White or Black, we don't know, but we can only hope. If not, we can always go with one of the many color swap places available. As February gets closer, the new will keep rolling in <b>...</b>

www.macmixing.com - Mixing it up with Apple. Today I am showing you an unboxing and installation tutorial for an Apple Logo Light Mod from lightmyiphone.com This is an iPhone mod that allows you to illuminate the Apple Logo on the back of your iPhone, just like it looks on a MacBook! I realize this is a LONG video but it honestly is the only realistic way I could show how to install it while explaining everything. It is fairly easy to install but is definitely not for the electronics beginner. This mod realistically requires a decent amount of time to sit down and install. DON'T try this in a hurry guys, as you'll screw up your iPhone. But if you follow this video it will help you get the mod installed. All the tools you need to install the mod are included when you purchase the light mod kit.This requires you to open up your iPhone and install a light panel which can be seen behind a special back for the phone that has a transparent Apple logo. The end result is very cool and well worth the time. I noticed a bit of light leak at the top, but that didn't bother me too much as it looked VERY cool once I put it in a "Logo Reveal" case from Seidio. BE PATIENT! I know I say this like a thousand times in the video but it's very important to ensure you install everything correctly and don't short out your phone. Proceed at your own caution, as macmixing.com or myself are not responsible for any damages you may incur during the installation process. Use this video sa guide <b>...</b>
