It should only have 1 profile... Anyways, I went through that tutorial step by step a few weeks ago, and my web is still flaky... Not just with MMS but say I watch a video on youtue then maybe 30 minutes later try and use Opera I get error messages. I have to either keep refreshing over and over til it works or go to the comm manager and disconnect the data session.
I'll do some searching and see if I can find the regedits I was talking about. It was never a biggie to me. Just a minor inconvenience that comes with having a bada$$ phone on Cricket
