So after watching Chris's video and seeing how he has had luck with a SanDisk microSD I bought one today. I bought the class 4 Mobile MicroSD 16GB. Installed it and have set the phone up and install all my apps back on and synced. I haven't noticed any issues so far so so I'm hoping it stays that way. It definitely seems faster than before I had the card but it could just me having wishful thinking.
