I'm in the Detroit Metro, specifically Southfield area and I haven't been able to get a steady signal at all for the past few days. I get full signal for calling, but data doesn't seem to be working. Data connection REALLY sucks, and this is only began a few days ago. I try to browse and it shows me full signal (or at the least, half) with 3G, and it will flash the up arrow under 3G once, and then again, and not do anything. Then after a few minutes I'll try again, and it will suddenly start working, and switch to H and I'll be able to use data, then it goes out again. I'm wondering if this is because I upgraded to Froyo, then downgraded back to my desire port from Modaco..I did flash all 3 older original radios, and none help the situation. So I'm hoping that it's the towers around here and that I didn't fry my radio somehow. Anybody else having similar problems?
