Doubts with A925

[pontxomanzanill]

Hi I´m a newbie in this forum and with this phone, too. Please, help me.

There are 4 main doubts.

I saw in a Nokia 6600 how his owner was taking photos with zoom and I ask if It's possible with a a925. I saw several apps like Camera FX which let you taking photos with zoom and apply effects later. I downloaded it, but when I try to install it the phone said to me something like "need to install Series60AppID"... what's the meaning of this?. There is some app like camera FX for the a925 to take the photos with zoom?

Second doubt.

About the battery. There is some software to manage the battery?. I mean an app that gives you information about battery in percetages not with "High", "Medium", "Low" whose mean talking about battery, is not very precise.

Third doubt.

Does somebody know what is the GPRS configuration for the Amena Operator in Spain. I need to know that because I´m going there on July.

And the last one:
I need to change the Network to make Video-calls, but the default operator is "3", and I don´t know how to change it. At this moment, I have no 3G service, this is the reason to change it.

Well... these are my doubts, Thanks to all, I wish you help me please!

Bye folks!
