I have only used a couple days. (I think it is too small for my hands).
This phone has a firmware modification that sets the data rate to full meaning you get stronger signals and better connections (When you get a phone from the cell companies that set the data rate to half which reduces your cell capability, but allows them to serve more customers from the tower. Also these phones are generally only tri-band, but can be unlocked for Quad band and this phone is unlocked to Quad Band!
I bought it for $280 so my asking price is firm at $250 but that includes USPS Priority Mail shipping with insurance.
This phone can also be used a broadband modem to you computer and has the fastest HSDPA 3.5g modem on the market!
It also includes Motorola Phone Tools 4.5 which enables you to sync with outlook!
A 1GB Micro SD card is also included
All the manuals and original packaging is included!
