According to CrackBerry.com:
Well, it's been a while since the BlackBerry Tour 9630 had a leak so here it is. This has been floating around for a while now and let me just say when other devices are well into the .4xx it's probably best you skip over this one. It took this long to show up for a reason, the reports are the radio is bad in this one meaning you likely will have connection problems if loaded. Either way, I'm sure some of you will still check it out, worst case just downgrade again. Don't forget to back up your device.
I'll pass on this one, especially since I got .230 working perfectly with my companies BES.
