T-Mobile BlackBerry Onyx 9700 makes a Bold statementThis article contains unofficial information.
Apparently, the T-Mobile version will have different specs than other GSM models like the one AT&T will be offering. With a different processor and using the same battery found in the Curve8900/Storm/Tour , the idea is to have the T-Mobile USA unit be exactly like the version sold by T-Mobile in the rest of the world. This way the phone could work on the carrier's 3G network in the U.S. and in Europe. The other fellows like AT&T, Rogers and Vodafone will not have to include T-Mobile's HSPA frequencies on their radio. More information is expected to be released in November and until then, let's just call it the BlackBerry Onyx 9700.
