Out of these four crads which one is good to use on the PPC-6700?

Kingston 2GB MiniSD Card, Mini Secure Digital Card, with Mini SD Card Adapter, Model SDM/2GB

Ritek Ridata 2GB 60X Mini SD Memory Card with SD Card Adapter, Model MSDCR2G-YLW

PQI 2GB miniSD Card with SD Card Adapter, Model AE16-2030-0112,

A-DATA 2GB Speedy miniSD with Adapter, Model MINISD2G+Adapter,

they should all work on the 6700 (I don't think the 6700 has any memory addressing issues with any 2GB cards). The real question you should ask yourself is if speed matters to you. If you don't care about speed and just want storage space, then get the cheapest one you can find. You should also consider a card with a long warranty (5 year or lifetime are common) just in case it malfunctions down the road.

I currently have an "OEM" brand 2gb miniSD card (from some random amazon seller) and I have no idea if it has a warranty on it. It's been working fine for 6 months, but I worry every day that it might randomly die on me since it isn't name-brand (at the time of purchase I just wanted something cheap).

Check out the prices on Newegg.com and amazon. 2GB miniSD can be had for less than $22 these days!

I'm not sure card speed makes any difference on a phone - though it makes a lot of difference with cameras. I think the inherent r/w limitations on the phone take away any advantage of a faster card. - sheureka
