Root Model Changed after rooting

[ragavendrang]

Hi All,

I have bought Samsung Galaxy 3 5 months back... the model no is GT-I5801. I did rooting to upgrade from Android 2.1 to 2.2 but the model no got changed to GT-I5800. Now my phone is dead slow... battery also got drained soon.

I really frustrated by using this change.

Can you anyone please help on this how to rollback all these things.
