Updating my verizon blackberry 8830 firmware
Callback removal app One Sim Direct is available for Jail-broken phones from Cydia.
One Sim Assist app will work with all i Phones correcting mis-dialed calls, though it will not remove the callback.
Though both Black Berry phones are in the same series of RIM’s device portfolio, the Black Berry 8830 isn’t just the 8800’s CDMA twin brother.
It adds a GSM/GPRS radio to the CDMA mix, making the Black Berry 8830 a two-flavored beast.
It does not require any compatibility settings and will work with any unlocked GSM phone.
If you are unsure whether your cell phone is compatible, please contact us to confirm whether your cell phone works with One Sim Card before making your purchase. May receive "call failed" error before the ring back, please ignore this message.

The Black Berry 8830 works on both digital dual band 800/1900 MHz CDMA networks and dual band 900/1800 MHz GSM/GPRS networks for use in Europe and Asia (the US uses the 850/1900MHz GSM bands only, which the 8830 doesn’t support).
But it loses some speed as it’s using a different processor than the Black Berry 8800.
You can use the phone on Verizon’s CDMA networks in the US, and when you travel abroad in Europe and Asia where GSM dominates you can roam using the GSM SIM card with Verizon’s Global Service plan.
