Gammu Phone Database grew into quite big size and there were quite a lot of duplicate or poor quality records. So I today decided to do some cleanup of data inside it. First step was figuring out duplicates. There were quite a lot of them and I could remove about 50 records without loosing information about any phone.

The quality issue is always harder. Some empty records really did not make a sense, so they're gone now. However some users really don't understand what some features mean, so there were quite a lot of phones being reported to support MMS and I'm pretty sure there is no code in Gammu for it :-). I went through their list and dropped almost half of phones there. Some records might have been useful in other way, but I can not verify what all was wrong with them.

Maybe I should add some basic checks when adding new entry to check such errors as MMS support for AT connection.
