Issues with Blogger

I have some issues with blogger, hope someone can help.

(1) Is there any way to insert jump break in all my earlier post, some script, anything ? I;m currently using javascript to compress my post on homepage, but it loads the complete page and then compress it

(2) If above is not possible, can I get the expandable post feed feature ( in email ) just launched by blogger without using jump breaks.

(3) Mobile templates, a nice feature but it does not auto redirect from techquark.com to mobile version on my Nokia N97. Many other people have same problem with their smart phones. Any hint on the same ? I have enabled it in draft blogger.

(4) On wide screens, my blog appears in the center and side areas are empty wasting lot of space. The same can be seen on this forum also. Any hack to fix it ?

Forgot to mention my blog link : TechQuark.com

1- You must edit your old post manually, one by one and insert the jump break
2- i don't undertend your question ?
3 - There is no redirection from Blogger - from your blog to a movile version of your blog. There are a couple of options for free to offer some redirection if a user is browsing your blog from a mobile. Unfortunatelly this options are really poor yet.
4 - that depends on the size and resolution of your screen. Things are made in that way so people with different screen sizes and resolution can see a website in the same way. Something that you need to bear in mind while designing a blog/website/forum

The fix to that is use % instead of px (ie 900px to 100%)
