I mentioned earlier in other thread also .. in india, you dont get good quality MMC easily.
N70 require DualVoltage - Reduced Size MMC
The one that comes in package is 64MB from Nokia, when I go to check out the higher size MMC from Nokia .. I cant find it. even I see lower quality chinese one available at Nokia Priority.
If you get those NCP/Samsung/Microsim .. local without bill, then even 512MB will hang & chances of getting it corrupt.
&
If you take
Kingston or Transcend MMC, then no need to worry 1GB willl work like a charm.
these comes with lifetime warranty .. So no-issues
