Right now I'm using a 1 gb sandisk memory card in it, but I'd like to bump up the memory so that I can put more then 100 songs on my phone. I'm looking at this card here: http://www.amazon.com/Sandisk-MicroSDHC-Memory-Adapter-Packaging/dp/B000SMVQK8/ref=pd_cp_e_0?pf_rd_p=413863501&pf_rd_s=center-41&pf_rd_t=201&pf_rd_i=B000Q8623U&pf_rd_m=ATVPDKIK X0DER&pf_rd_r=16QBQPKXK4N52KWJYJM7 , but I've heard a lot about razr's failing to accept more then a gig of memory. Any help?
