Interesting, I've never thought about Bloglines. Basically, you have to do the following to get around the form with iSiloX:
Set a cookie with the following information:
Name: BloglinesMobile
Value: 1
Domain/Path: bloglines.com/
Expires: Never
Make sure that "Send" and "Receive Cookies" are both enabled (checked).
Then use the following url as the channel url:
http://www.bloglines.com/login?r=%2Fmyblogs_subs&email=<emailname>%40<email address>&password=<pass>&Sign+In=Log+In
whereas for your login information
<emailname> is the part before your email
<emailaddress> the part after it
(i.e. emailname@emailaddress)
<pass> your password
This should get you on the mobile main page. The PROBLEM with using any kind of offline browser is that if you are not careful, it could UNSUBSCRIBE you from all your feeds. You would have to exclude certain links from iSiloX, such as
http://www.bloglines.com/myblogs_subs?removesub. But there are also other problems; for instance, there are links that would mark all your already read feed items as unread again if iSiloX parses them.
So be careful with using an offline browser for Bloglines. I am currently working on a system that should allow you to automatically convert RSS content to mobile content. In the meantime, I suggest you try a similar service that already exists:
