SD Card Maximum for Apache

[timskoog]

New guy question: Once using the kitchen to upgrade a Verizon 6700 Apache to Mobile 6.1, I understand I can use up to a 6gb SD mini card. First, is that correct? Second, can it be SDHC? Third, can an 8gb be used, and will it function up to the 6gb limit? Alas, I've found 8gb cards cheaper than 6gb cards. And, remember that this Friday is "Talk like a pirate day".
