Now I might just have to return my G1 and wait for the "new" Clearwire, Sprint, or other service if T-Mobile does this. I need to stream live video from security cameras at my house 24/7 to my G1's browser and I only hope I dont hit that limit because if I do, I will be leaving what has otherwise been my favorite company.
You can be sure that ANY wireless internet will have caps. At least this one's a soft cap that just bumps you from 3G to EDGE speeds if you go past it.
I also doubt that ANY provider would be happy with 24/7 streaming video to a phone. That's not what they're made for.
