N80 SMS problem/restarting (!?)

Question

hi.
I have a few problems, i don't know if they are linked.
I'll start with a background story. I had UltraIMpro, and F-secure anti-virus (both trial versions) on my N80, both had run out of subscriptions. I noticed that my phone had started to restart tself a lot, sometimes about 3 or 4 times a day, i knew it was doing this because that F-secure screen always appeared after it had restarted, asking me if i wanted to do a scan, as usual! I always just exited the program, and have scanned for viruses, there arent any!
Anyway, this Restartign thing got annoying, and then another thing introduced itself! I was with some friends, and both of them said they had texted me earlier, but i hadn't received them. The next day, i turned my phone off, and when i turned it pon again, i got the 2 text messages. These messages did not appear when the phone restarted itslef, but only when i turned it off myself. This happened once more, after which i got **bleep** off and decided that maybe i should back-up my data on my 1GB card and hard-reset the phone, maybe this would solve the problem i thought.
So, one night, i tried to do this, and i got the error message "Memory card full : close some applications and try again" now, i have 540mb free on this card, and no applications running on the phone. Even right now, it wont let me make a backup, Could anyone explain this??
So, having failed that, i wondered if these extra applications were annoying my phone, so i uninstall the useless ones, F-secure and UltraIMpro, and surely enough, i go and run a few tests, and the SMS's seem to be arriving fine and imemdiately. Is that logical at all? Is there a phoesable explanation for this?
I can't tell if that has fixed the restarting problem, as i uninstalled F-secure, which was the only thing telling me that it was restarting, but i haven't seen it restarting yet, so i also hope that problem has blown over.
So, basically, i was just looking to see if anyone could help me with this memory backup problem, and if someone could explain all of this gaffuffle!
Thanks!

Answer 1

ok lets start:
restarts.....delete all apps on the phone including themes etc.(use pc suite to save what you need on your pc)i believe this prob stems from the f secure trying to still read your system and cant cause its a trial so its not completing the operation and basically hindering the other apps
text messages- n80 has a lag in sending text some prior users have complained that it freezes for 40secs when they sent text messages.....please dont worry about this its a firmware problem/bug which if you go to a nokia service centre it can be upgraded to the latest firmware in the uk...be patient as well as nokia has also introduced over the air and downloadable firmware upgrades....unfortunately the n80 is not yet available....so its nsc or wait until it is(it is very easy to do this as ive upgraded one of my older models which is available.....click on home on the top of this page and at the bottom left there should be some info on this)
memory card- i have found that certain cards do not work well with mobile phones i suggest sandisk which sem to work well with mobile phones.....that memory problem seems to have been a bug to others i didnt have this prob(2gb sandisk memory card) so i guess this is dependant on the actual handset some give this prob others dont.....firmware upgrade is expected to change this hopefully.....
lastly as said in the first answer save your stuff to your pc and then you can master reset your phone this helps as well (press *#7370# on the active standby screen) but remember all data will be lost including contacts so save everything!!!!!
