I have a unlocked tmobile 9700 white. Im useing it on a&tt and the 3g wont work. only says EDGE. why?

Answer:

Unlocked is not the same and unbranded. If it was BUILT for one carrier, it's hard-coded down to that frequency. There are some people that say that with software that is illegal to own outside of RIM's factory/labs, you can get into the engineering code and change it. And, there are those that say it's the physical chip in the phone that does not have it.

Either way, if a phone was branded to one carrier, you can unlock it to work on other carriers, but not on all bands.

UNBRANDED phones have never been locked down to any carrier and should have all bands available.

Unlocking the new Blackberry Bold touch 9900 and 9930. I think we can all safely say this will be Blackberry's flagship device of 2011 and we at unlockmybberry.com are very excited about this release!!

The new Blackberry Bold Touch 9900/9930 will be and is 100% UNLOCKABLE!!!!

No matter what country & carrier the phone is locked to; T-mobile Verizon At&t Rogers Fido Telus Bell Koodo Mobilicity Virgin Mobile Wind O2 Vodafone Orange etc...

You will be able to INSTANTLY unlock your phone by either getting the Unlock code from us, one of the other great unlocker's on Crackberry, or even calling your carrier... the options are endless!!

Now the process of getting your 9900/9930 Unlock code is simple, fast, and the exact same as all other blackberry's......

Just retrieve the 15 digit IMEI out of your phone by typing in *#06# into the dialpad and give that to whoever you decide to get your unlock code from...

Once you receive your code just follow the simple unlocking instructions provided by your carrier or the unlocking company and you will have your Blackberry unlocked in MINUTES! It's simple, takes no technical knowledge, and ends with you simply just typing in the unlock code into the dialpad. It will say "Code Accepted", the phone will pick up your new network, and your ready to go!!

Once unlocked....

You can use your phone on ANY Gsm Carrier in the world!! Also, your phone will never re-lock, it won't void the warranty or harm the phone, you can swap sim cards back & forth as you like, it's 100% legal, & it even raises the re-seller value of your phone!!
That is how to unlock your Blackberry Bold Touch 9900/9930.

So my dad works for boeing and he gets new blackberrys (blackberries?) every year and so he has some just chilling in cupboards. So i picked up the 8700c that he didn't want. The problem is that its a Cingular phone. So i need a way of changing it over to either Sprint or T-mobile. Any help would be greatly appreciated. Thnks


Answer:
There are several online vendors that can unlock your 8700c such as www.unlockmybberry.com, but you will not be able to use it on Sprint. Good luck!
