sim question

[flylikaG2]

Received my g2 last week, and speeds are no better than my g1...I'm in san diego where the new network is in effect, so I'm wondering if it has anything to do with the fact that I'm still using my g1 sim card instead of the new one that came with the g2. Years ago I wasn't able to get service at all in the las vegas area because of an out of date sim card so I'm thinking this is a definite possibility. Any input?

I've read in a couple of locations that G2 owners should be using the new SIM that arrived with the phone. Personally, I'll be new to T-Mobile so I'll only have the card that arrives with the phone.

When I was buying mine, (returned because of no wifi tether yet, waiting on perm root), they said I had to use the new Sim, don't know why....

I'm using my old G1 sim and haven't had any issues and am constantly getting good speeds on H. I'm inthe new york area.
