EVDO speeds and Support wanting to refresh aircard

[gthsii]

Setup: I've been running JDs test ROM and enabled GPS and EVDO Rev a for about 10 days now.

Got a question: my data speeds dropped from the 1300kbs I was getting for the last two weeks down to barely above dialup speeds (anywhere from 50kbs to 182 kbs today-it was fine last night). I called Sprint support and they said all towers in my area are fine (but his first comment about whether they were having data issues was a Yes from the support guy). My phone shows full bars and EV icon. The support tech offered refreshing my air card, I turned him down and said I'd call back later if it was still an issue. I turned him down because I was not certain what his refresh/reprogram attempt would do to my unlocked-re-rommed phone.

Anyone know if their attempt to reprogram the aircard would -
1. expose me as a rom hacker?
or
2. break my custom rommed phone?

Thanks,
GT
