BLACKBERRY

This Tab is dedicated to Black-Berry of GSM and RIM (CDMA).

WHAT IS THE DIFFERENCE BETWEEN CDMA AND GSM?

CDMA Carriers (Sprint, Verizon, Alltel, Metro Pcs, Qwest, US Cellular, Helio) don’t

require Sim cards to have wireless service, but instead use the phones Electronic

Serial Number (ESN). GSM carriers (AT&T, T-mobile, Movistar, Telcel,) have SIM

Cards (Subscriber Identity Module cards) that the phones use to communicate with

cellphone towers. The two are complete opposites of each other.

FLASHING

Flashing process is the same process as you used to do for NOKIA Phones. But, the

different of Nokia and Black-Berry flashing is that you can’t downgrade firmware in

Nokia Phones but you can downgrade or upgrade (ROM-the Flashing File) firmware

in BlackBerry Devices without any tension with this Tool. PB Tool supports all the

Devices (Blackberry Mobiles -Rim & Sims) for flashing and has the solution of Jvm

error, jum error 543 and red-blink of 9900 and 9860 which could not be done with

the Desktop Manager. But, all the Red Blink OS7 could not be solved by it. But, this

doesn’t mean we are not working for it, we are working we don’t have good sleep for

its improvement. PB has solved the error 507 (shown in BB 9360 and 9700) after

flashing but PB Tool doesn’t not supports De-Branding (changing start up logo) and

Multi-Flashing yet but we have made the Concept for upcoming update.
