Guys,
I want these apps for my Nokia 5800. Can anybody tell me the best s/w for my nokia 5800..??

1) SMS locker (I want to make my GF's sms private in my cell like SAMSUNG mobile has)

2) SMS export in TEXT or HTML format (Like SMS diary for s60 v3 devices has)

3)Some useful apps like Indian Train inquiry, Flight status.

By d way, also i've two problems in my cellphone.
