    Its really surprising that the phone doesn't come with a keypad lock feature. Just because it is a flip phone, doesn't mean that the uses won't like to have a keypad lock feature.

    If anyone knows of any workable software or a trick for this software, kindly let us know about it.

I dont wish to sound rude but you people r idiots, the reason y most phones have keypad locks is so that u dont accidentally call someone whilst ur phone is in your pocket,, FLIP PHONES DONT NEED THIS KIND OF LOCK. I work for in aphone shop here in thre UK, so I shud know. Dont agree?? Take it in to ANY phone shop and ask them.

Dear Freinds,

I have Z550i by mistake it droped in water for 10 minutes. I make it ON after soaking for 4 -5 hours. Now it is goiving humming sound only when we recieve calls (during active network link with other person) from other side or when we dial someone. In simple on condition there is no humming sound. Also it is discharging soon. MP3 songs and radio is working fine. When I put it in charging it shows that your USB port is active and reday to data transfer. I am unable to understand what is the problem.

Please advise a best solution .....
