well congratulations on getting this to work, despite the overwhelming opinion that these should be rightfully left to die. perhaps frostwire is right for android, but not n900, all the same every new app is welcome!

for those asking about memory, the way p2p software like this, or torrents, downloads data in random order and writes to memory in pieces is bad for flash memory, if the n900 senses a corrupt block it will set that memory to read only and it will need formatted. so definately set all p2p programs to download to memory card rather than phone memory to save any major hassle when you encounter corruption. there is a program called flashlite which looks to adress the p2p flash corrupting problem, but i dont know if this would be compatible with frostwire on n900, i'll stick to torrents myself for now.
