Big Storage+128 sd card

[nm8]

Hi folks

its me again wanting to ask a few questions before i get my hands dirty.
after upgrading my radio version to 1.13, now i want to go ahead with Big storage.
first question is do i really need a 128mb sd card, or can i use my 1gb sd?
question 2, will this big storage hack be applicable with my imate NEW jam? A.F.A.I.K, the big storage hack was used with previous models.

3rd question, if i fail doing the big storage hack ( or i encounter problems during the process), is it possible to revert back to my imate's original state?

thanx in advance

U can use 1GB SD card but U will have to work with files as large as your SD card size. As the matter of fact there is no problem with keeping backups - winrar can shrink it down to less than 100 MB AFAIK.
