Cseries :: C5-03 Can't Change Message Memory To Memory Card

I have to admit that I been in love with my C5-03 since the first time I saw it. But unfortunately, the phone gave me real hard time.

1- I can't change the message memory to memory card. It works for a while, and then an error message pops out, statimg that "memory card not found" and that the phone will revery the message memory to phone memory.

2- The phone memory is almost full. I have 11.4 MB left, and I don't know what's filling the memory. I have 3 apps installed, 1 MB each, besides the default apps. Browsing the memory was of no help: almost all folders are empty. I tried emptying the browser's cache, but 11.4 MB is all I could have.

3- Nokia store and the web browser give me the "memory full" message after a couple of minutes of browsing, and then they close automatically, making them almost useless.

4- The battery life is not impressive. I have to charge the phone every 1-2 days even with light usage (15 min of calls, no Wi-Fi or music playing).

I love the phone and I've been having it for 6 months now.I have installed the latest firmware 2 months ago (v.20.0.024, version date 25-05-2011.
