before installing ios7, i was able to use the personal hotspot feature on EDGE, but after i changed to 7, i can only use that feature on 3G... is there a way to get around that restriction? i know Apple did this to help you save on data usage, but come on?

I haven't been on EDGE for a long long time...

BUT.. i just turned off 3G and enabled hotspot. It enabled without issues..
