I have been lurking in the shadows too long, searching for just my precious...
Sometime ago i read someplace here that it is possible to get GPRS/EDGE data without getting a BIS/BES account on blackberry...
(yeah, call me cheap but thats how i like it.. no strings attached!)
Just managed to get my hands on one of them elusive cellphones. Its a Curve 8900. Just got it used from O2, unlocked it, wiped it and browser is getting edge data without a hitch :-)
Just installed google app for blackberry and it is working.. i know some apps do need BIS/BES service book entries but i hope to get them working soon too. :D
