The list is increasing again:
1. Fix the bug in sudoku
This was not a bug, but the grid I was using was awkward enough :P I tried the sudoku posted on http://www.sudokuwiki.org/Weekly_Sudoku.asp and it come out within a few moments with error.
2. Write a sms shortening app
3. Write an sms splitter app
4. Write an app which can transmit the phone data to pc via usb and can talk from the mic (way to ambitious :P)
