I know the earlier version of yellowsn0w had some sort of problem with 128K SIM cards and I am wondering if it still has that problem.

I have one of those cards and I should get 3G but I only get edge. Whenever my phone goes into "no service" the field test app says im connected to 3G but it says "no service" until yellowsn0w turns airplane mode on automatically and once i turn it off I get signal but with edge or no data at all. Could this be a side effect of having a 128K-A SIM card?
