Unreliable GPRS connection

[Guest plguzman]

My i8000 always connects to internet, and very fast. But a lot of those times (like 30%) there is no transferring at all. I need to shut down the connection and start a new one. Then I can navigate. My network parameters are good (access point, etc), and my i900 connects without problems everytime.

Is anybody else with this problem? Is THAT unreliable the GPRS connection in this phone?. I already flashed phone.bin from DXIJ1 to XXJA3 and back, but the problem continues.

Any tips I should know? Thanks in advance.
