If you are on 3G this is normal as it cannot do voice and data simultaneously AFAIK.

3g the data does not disconect, but as u updated and said edge, you are actually on 2g and yes, edge/gprs does drop data connection whilst on a voice call. even drops when a sms being received/sent. This is on all mobi's.
