It’s no surprise that T-Mobile tends to use the odd frequency out when it comes to various bands. They largely operate on the 1700 MHz AWS band. And for the most part, unlocked and imported devices along with AT&T unlocked devices like the iPhone tend to only benefit from Edge speeds, mostly relying on a decent WiFi connection. Well, all of that is about to change as Magenta is beginning to roll out their 1900MHz frequency. Now, users with unlocked device may begin to see the new 3G frequency on their devices where before only Edge speeds were capable. This is all largely in part due to T-Mobile upgrading their network to support existing customers. So, if you’re in the right place at the right time, iPhone users on T-Mobile could start seeing the new 3G signal soon. And with the recent fall-out of the AT&T/T-Mobile acquisition, Magenta will acquire certain spectrum licenses, in addition to roaming on AT&T’s 3G network. And how can you do this without proper hardware? You can’t. So, what’s in store for future T-Mobile devices? We’ll obviously need to see some handsets coming out which will support all necessary frequencies like 850, 1700 and 1900 MHz. Difficult but not impossible as there are a few Pentaband devices on the market today. Only time will tell however.
