updated with CSL 2.3.4 and rooted
Thanks to paarkhi, It is guys like him who take effort to share and inturn make life much easier for others.
For updating I used the SD Card method. Did not have to remove even the sim card. Took a little backup, but basically finished off in a few steps. Wiped the cache too.
rooted using the clockwork mod recovery. That also went smooth. as per the steps given. Remember to read the last line which is nearly a footnote.
CSL 2.3.4 is not much dramatic change in the RAM and running applications. I was irritated to see things like blueberry messenger and store. There was some S unno and Myriad UPnP server and remote.
system info app showed the following data for memory before and after the update
60 % used 142.8M available
57 % used 150.3 available
Removing the bloatware.
Somehow I dont know but have always not got the thing right in Titanium backup. When I rooted my Samsung mini sometime back got stuck with Titanuim. So I have gone for Root Uninstaller. Its working thought it has no yet removed the Blueberry messenger and the CSL funclub. I am being a little careful as to which app to remove.
Android market for the PC.
The only way to access is the webpage of android market through the browser. There also you can only send it to the handset, but cannot download it to the PC. Though it seems logical to have an itunes like setup to transfer apps. There are a few websites out there which allow you to download app to the PC. But thats about all.
There might be some plans in the future, but I have generally observed that android OS does not tie you down with anything in any aspect.
