Will my data limit on AT&T get reset once I upgrade my line to the 5S? I plan on keeping the same 5GB tethering data plan. I've used a ton of data this month, and it would be nice to get it reset back to zero, otherwise I'm definitely hitting some overages. Reason: Waiting 2 weeks for internet installation, and been tethering a ton off of my phone. Thoughts? Anyone remember how AT&T has dealt with this in the past?
