I've finally got a 1G memory card for my Nokia! Transferring data from the old card was a headache and I'm not yet through with it. I've also discovered that there's a severe paucity of good software for the S60v2 (my version). There's even a great BitTorrent client available only for the latest Nokia smartphones. That disqualifies mine.
And the 6681 had made its worldwide debut only in mid-2005! I was the envy of my friends and colleagues when I had newly bought it in July last year. It now almost qualifies for a vintage! How time flies!
I only hope Net access through my phone works as well as I'm imagining it should.
