Finally I have decided to put an end to all my frustrations with Nokia 5500 Sport. I have given it to the Nokia Care center to get the keypad replaced. It is going to take 20 days for getting it back. I have decided to sell it off once I get it. In the meantime, I grabbed a Motorola ROKR E6. I chose this one because it runs on Linux and supports a lot of mods. This is my first move out of Nokia to any other mobile vendor. It is going to take some time for me to get familiar with the new device. Thanks to Nokia 5500 that shattered my love for Nokia!
