Quick update: $30 for new SIM at Best Buy and I’m good to go! Thanks for the info, Mobilist.

But I did notice immediately that her iPhone SIM is 3G despite the phone itself only supporting EDGE, so it seems Mobilist was right. I’ll have to see what I can work out with AT&T to get a 3G card without changing data plans, or how cheap of one I can get.

If the iPhone SIM is removable, I’d like to know how.

I’m sure it isn’t, but I thought Jenn at pocketables had said she used her iPhone SIM in her Advantage and it just limited it to GSM/EDGE/GPRS use.

Keith,

Make sure your sim card is a 3G card since the Advantage is a 3G device. It should have the orange 3G fireball on it.

I have a non-smartphone SIM card and unlimited data plan, but it won’t even let me make phone calls with it.

Like James, my AT&T SIM works fine (from my Tilt).

Interesting – I can report that within the last week in Connecticut I checked the Manchester CompUSA and found Advantages on display for ~$800 (which was marked down from about $880). I’m going from memory on the $$ — but I’m withint +/- $20 I think.

I stopped at the Orange, CT CompUSA store on Boston Post RD on Friday night (12/28) and they had no Advantages displayed. I did not inquire.

For some bizarre reason sales were VERY light at both CompUSA stores. A lot of people browsing but not many buying. The prices look like regular everyday pricing – especially when compared to the web. I think CompUSA will have to go 75% to 80% to clear their stock. They have a lot of really generic stuff that isn’t going to be price competitive without a huge markdown.

My guess is they’re going to offload what they can then sell the rest to a liquidator rather than keep their stores open for a few more months only to sell stuff at a loss.

P.S. – The store in Orange is nasty dirty. Manchester CT is ok but nothing to write home about. I won’t really miss CompUSA – they were primarily useful for last minute stuff – and increasingly Staples and Office Depot are filling that niche.

My problem is now trying to figure out why my AT&T SIM card doesn’t work with it, I’m not in a hurry to go to AT&T for help and have them decide I need a new data plan.
