[Q] Do i need a external sd card for installing a new rom?

---

Maybe to backup all storage to internal sd card is not enough. BEcause its size is 2 gb.

What do you say about that? Do i first buy a sd card for a better rom changing?

Full rom backup size is a little over 500mb you should be fine starting with 2gb / + internal 2gb.

You say 2 gb internal is enough to backup phone memory and rom? I have 1.5 gb free memory on my internal memory.

Should be enought. You should take full backup too with linux. There is a guide to it here in general section.

I want to backup system data, desktop settings widgets, applications cache , call logs, sms. What can i use?

Use CWM. All data will be saved (except external SD sata like phone, music, etc)
