T-Mobile 8900 188.8.131.528 works almost perfectly with all of my apps including Doc to go 2.0, BB 5.0 Messenger and so far, Facebook. The only program that I am having problems with is QuickPull Pro but the free QuickPull is working well. Waiting for a revisionof the Pro version.
It is VERY fast, clean and I have not had any reboots at all!
Anyone else out there having a successful experience with this version???
