I was playing with SMSCON and locked the handset. I didn't know the unlock code, so I had to flash the handset so that the phone would stop looking for it.

How do I get my applications back now? I have tried to re-install them, but any apps (like the SMSCON editor) that where previously installed are giving errors. Is it possible to 'ressurect' the apps already installed? It would save me having to configure them all again. If this isn't possible, what can I do to get my apps back?

I'm sure this has been covered before, but I can't seem to find anything using the search.

Just backup necessary files i.e. contacts, movies, music etc. Then do a complete reflash. In which case applications will install fine
