Eten Glofiish x650 data

[kameraman]

Hello!

First of all, sorry my english is not to good.

I bought a used Eten Glofiish X650 win mobile 6 PDA/mobile. I used at this point an old Yakumo Delta PDA. If the Yakumo's battery went empty, my datas (connects etc), and programs lost.

It is the same method with this Eten too? Because I afraid if I change SIM card when I take out the battery from the PDA, my datas and installed programs will lost. But it is the only way to change SIM card.
