I am very pleased with this memory card. It runs perfectly. I could no speed loss what to access from your phone to the memory card concerns over an MMC card of Hama notice with 128MB. My phone list data, regardless of whether MP3, photos, etc. perfectly by this etrememory MMC card. In an N-Gage the memory card is recognized, they have not been extensively tested allrdings there. I would recommend people looking for a convenient MMC card looking for his cell phone, at least Nokia 3650 access here.
