Thanks! I called them and they agreed to send me an Airave and waive the $99 change, however I would still have the pay the $5 montly useage fee. They weren't willing to waive the month fee since I am on a SERO plan. Strangely, they also said that I was in a Nextel area and that I could switch to a Nextel plan. I told them I wasn't interested, and I was actually surprised because I thought Sprint and Nextel merged a few years back. Why would they still be operating seperate networks? Strange!
Anyway, the nice customer rep told I could upgrade to a new 3G phone for an additional $10 or a 4G phone for $20 more than my current $30 SERO plan on October 1st. I know the rumors have been floating for the past few weeks, so it's nice to get it straight from Sprint. I think I'll upgrade to the Samsung Epic 4G on 1 October.
