Ok guys, I'm about to flash my N900. Before proceed, i would know how to save the conversations already had with some contacts, is there a some kind of archive that I can export to backup all these conversations? Oh, one other question: I read somewhere that reinstalling yappari on a phone already registered can cause some kind of trouble validating the IMEI for the second time. How can I solve this issue? I'm sorry for these two questions, maybe someone have already asked something related, but I'm not so good with english language and often I can't understand some topics d!
