1.Is there a way to change size of partitions without flashing new rom?
2.How big the partitions should be (System, Data, Cache) ?
According to "Blade Checker" I have European ZTE Blade 512MB, Gen2 phone, also it said that I have to use image.bin style TPTs.
Curent partitions are:
It is running CM 7.1 stable mod and Clockwork Mod Recovery 188.8.131.52
Thanks in advance, and I am sorry if I posted at a wrong place.
If you changed your partition sizes, your rom and all your data would be wiped. If you made a backup before, you could restore it afterwards as long as it could fit in the new sizes (eg. if your rom took up 160MB in system just now, and you changed system to 170MB then it would fit so you could restore it, same for other partitions).
Size for the partitions depends on what rom you are wanting to install. Some like Swedish Snow can fit in 128MB system, others like the ICS ones need ~180MB or bigger.
As your current layout is big enough for any rom out now, you'd be better making an ext partition on your phone and using that. S2E from Google Play works well with CM7 and lets you move most, if not everything, on the data partition to the ext partition. Its usually best just to move apps, but it means you can have loads of space. You can choose the size of ext partition depending on how big your sdcard is and how much space you need.

2MB is the minimum for cache. You can redirect the market downloads to data/ext partition/somewhere else, so you can download any app you like. Most roms do this automatically if your cache partition is small. By making it bigger than 2MB, you are either wasting the extra space if its still small enough to be redirected, or you are restricting the size of apps you can download if its too big to be redirected.
