She has a 7250 now

From my user:
You get a loud buzz, static, noise interference, one cannot make out what the other party is saying. If I can find a technical article, I will email it to you. FCC mandates that M3/T3 ratings be offered by each provider on one phone that they make.

What are the M and T ratings of the Blackberry 8800? No one can tell me because they say it is not on the spec sheet. In general, M refers to the microphone interference with the hearing aid. T refers to the hearing aid compatibility level. M4/T4 is the highest rating.
