Verizon appears to have locked down the 850MHz and 1900MHz bands on its new Motorola Droid 2 Global handset, which essentially makes it impossible to use the device on AT&T stateside. Granted, Verizon clearly markets its worldphones as only capable of 900MHz and 1800MHz compatibility — presumably to thwart exactly the type of network-hopping usage that the hardware technically facilitates — so the end-user can’t really complain of false advertising. Still, the temptation to use worldphones on domestic GSM networks is a strong one, and phones like the Windows Mobile-powered Touch Pro 2 now require but a security unlock and radio flash to enable the locked out bands.
Apparently the Droid 2 Global lockdown only affects US usage, as a Droid Forums poster has already reported successful use of his phone with foreign, 1900MHz SIM cards in Peru — he was, however, unable to acquire a 3G signal. Since the D2G along with the Droid Pro are the first Android-powered worldphones on Big Red, this is still an area that’s relatively unfamiliar to the development community; that being said, we can’t imagine that a software method of unlocking these taboo bands is too far away.
