I"m planning to buy the BB 9700 and i found one at a good price used but its for ATT, I'm going to Unlock it to use it for Tmobile.
My question is Once i unlock this phone will i be able to use the 3g network of Tmobile? I know this Phone supports 3g and my concern is that it will not work with 3g only with edge, Just like the Iphone 3g only can get Edge with Tmobile because of Frequencies.
Can anyone confirm this please i need to know before buying this phone.
AT&T Blackberry Bold 9700 works on HSPA 850/900/1900/2100 MHz. T-Mobile has recently acquired 1900 MHz spectrum for 3G and 4G and thus they've iPhone now. You can buy the phone and unlock and use it on T-Mobile with 3G service. But you'll also need Blackberry Plan for the 3G to work.
