Just switched to Verizon for the Droid and now finding that the Droid has problems merging calls when adding a person to a call to have a 3-way call. Completely frustrating when on a business call. When you add the new caller, the merge calls button does not show up sometimes, but rather the swap calls. The screen locks up and the add call button will not work either. Have to drop the calls and use AT&T phone.
