Hello, new to this site and my PPC 6700. I just recently purchased a 4GB SDHD Mini from this site(http://www.flash-memory-store.com/qm...e-digital.html) for my 6700, it was the second of two cards that i purchased for my phone, the first was a 2GB SanDisk card that did not work on my phone. When i first tried my new Qmemory card my phone would not recognise the card, and i felt like i just wasted another $100.00, but i then moved one picture to the SD card using the provided adapter from my desktop computer, and then my phone was able to read the card. I did not apply any firmware upgrade or install any additional software, and my phone was able to read the 4GB SDHD mini card, oh and to be sure it was actually a 4GB card, i transferred 3.97Gb of information to it. Hope this information helps all of you looking for the ability to store more on your 6700.
