I use a 1gb Kingston MMCplus in my 6230 - works great you can get them for
about £15 from Ebuyer or Dabs.
The 6230 can handle bigger sizes - 2gb or 4gb check out
www.mobymemory.com
they guarantee that cards purchased from them will work - and they sell a
great USB pendrive that takes the MMC cards and doubles as a data stick. You
def need a card reader of some kind as filling any of these cards via
bluetooth or the Nokia data cable would be torturous!
I think 1gb is the perfect size though because the most files you can have
in a playlist on the 6230 is about 197 - though you could have several
playlists created with Nokia PC Suite if you want. I can't be bothered with
playlists though so on my 1gb I have about 180 full MP3s (about 12 hours)
plus a couple of half-hour videos. Use the random function in music player
and you get an Ipod shuffle for £15 odd!
The 6230 and 6230i use standard MMC cards - but MMCplus and RSMMC cards are
backwards compatible (adaptor needed for RSMMC), so will also work fine.
Although you will not get any advantage using MMCplus on the Nokia, it makes
a big difference using a card reader that supports MMC plus. The 6230 will
not use the extra contacts on MMCplus or RS-MMC. The only reason to buy
RS-MMC is if you think you might upgrade to a phone later that only takes
these smaller cards.
Prices are so low now why not go for 2 x 1gb cards so you can swap them
around and change the tracks quicker!
