Yesterday my external slot Transcend 2.0 GB 150x card corrupted again transfering a 21 MB PDF file via FTP (WiFi). It's the 10th or 11th time it occurs, with all the differents firmwares since I purchased my device.

So, how can I contact with technical service at Nokia and get my unit replaced with one like yours? I purchased it on-line, at Nokia store, here in Spain (Europe)

I want to be able to use maemo mapper (corrupts the card if I download 10 or 20 maps), transfer large files, use it with canola, etc.
