Not sure how to phrase the question properly, but basically I'm wondering if there exists a mod where you can force an iPhone to connect to a specific AT&T network (GPRS/Edge/3G) rather than allowing the iPhone to connect automatically to what's available. I travel often to Vegas for work and the Edge/3G networks there are quite literally useless. GPRS is slow, but I can at least make calls/text. Anyone know if there's a way to do this? I've been looking for something the last few days but can't find anything. I know it was possible to turn off the 3G radio back on previous iOS versions, but obviously GPRS and Edge use the same radio, and it'll default to Edge most the time. Thanks in advance!
