Updating blackberry 8310 os
I am a little bit of a gadget junkie so a cool phone was mildly important. Maybe they vary from city to city but the customer service and tech support at the store I visited was far superior to anything I have received from AT&T.

Unlocked cell phones are mobile phones that can be used on any GSM network with interchangeable SIM cards.
Some carriers offer free calling to a number of contacts or one-button access to certain features that can only be used on locked phones.
Consumers concerned about specific features may want to check with a carrier to see if they are available on unlocked cell phones.
This may be a concern for international travelers especially, since not all bands are used in all countries.
For example, in South America, the 850 MHz band is in common use, but others may not be available.
Third party services are also available to unlock a person's cell phone for a fee, usually by attaching it to a special piece of hardware specially designed for this purpose.
In many cases, unlocking a phone is just a matter of activating the phone and entering a specific code; some phones, however, require a series of steps before the code can be entered.
Not all codes work, and trying to enter codes that are incorrect can cause the phone to "hardlock" and prevent it from being unlocked.
Certain models of cell phones can only be unlocked using the hardware method, which may also work for hardlocked phones.
Some cell carriers sell unlocked phones at full price, usually allowing consumers to pick a flexible plan such as month-to-month or pay-as-you-go billing.
This can provide access to carrier-specific features with the flexibility of an unlocked phone.
