i cant send or receive messages from my mobile, sony ericsson w100i . "Message Corrupt" is the message given when i open my inbox in a conversation mode. in normal inbox i can see an empty message. Before a week it showed "Out of memory delete messages" displayed. And i bought this mobile only before 2 weeks ago.. Please solve my problem.

hello,when it got damaged by dropping into water,did you try to dry up the panel before putting it on,if not that would have affected the panel and also the battery,does the phone still power on,if no,you will have to get a battery from a store or a friend who uses same kind of phone to run the test in powering it on.since the screen does not display any longer i suspect the screen is faulty or the pones flex,so you will have to get a new one
the assumed estimated cost for both the screen and flex is about 30-50 dollars,
please kindly rate the solution if it's helpful,

take care.

hai,
it seems your mobile phone and the SDmicro card are infected with some virus. try software upgrade using the PC suit

well you should just take it back to the store you bought it from and have it fix or replaced.

Put extension phone on base unit; press menu; press 0 0; press and hold intercom until charging light starts flashing. the display should show OK on the display screen of the extension phone; press OK. If you have more than one extension to add:
after you press 00; the symbol for # # # will come up. Enter a number for that extension i.e. 2; 3; or your choice.OK will come up on display at bottom right of display; press ok. hope this helps. This info should come on the extension phone and "menu" is on ext. unit. So turn the display up so you can see it while it is on base unit.
