I wonder, what do you feel to be the biggest handicap of 770 - the small memory or short battery life?

I mean, would you agree to increase memory to 128m but decrease battery life?

Would you agree to keep memory the same if Nokia comes with better battery, or would you prefer to keep the battery life the same but increase memory?

When do you feel that memory is not enough, what applications are you using at that time?

Why ask...I mean, what are you waiting for? When you brick your 770 I can guarantee you that it will remain a brick--no reflash for the hardware mistake.

... But perhaps someone else is interested on solder.net service (I'm assuming here that they accept replacing the 770's BGA 64MB DDR mobile RAM chip with another 128MB (for instance) chip provided by you, all by $50 plus the cost of the 128MB BGA chip).

Anyone crazy (and rich) enough to try ?

And of course, I know what means "hardware"-bricking a ~400$ gadget, so I will not do it

PD: I'm also assuming that, according to earlier posts, the RAM chip is BGA, anyone has high-res photo's of the 770's PCB and IC's apart from the one posted earlier ?

Are you sure ? According to:

http://www.samsung.com/Products/Semi...4&cd1=&x=6&y=5

All memory part numbers start with "K4", ok, I understand that it could be a typo (A for 4). But I cannot find the rest of the part number on samsung :_/ Could you try to reread/find a matching datasheet on samsung ?

Here is an easy to follow part number guide:

Thank you !
