If you want your mobile phone site listed on MobileMentalism.com, drop me an email with your URL, and I'll see whether it's suitable or not. I have a few rules your site must comply with first:

1). High quality information only. You must provide new content at least somewhere on your site, not simply reblog everyone else's work.
2). Full and proper credits of your sources. If you do re-blog other people's work, do the proper thing and link to the source - don't pass it off as your own.
3). No overtly commercial sites. If all your site does is sell mobile phones or offer affiliate links, look elsewhere.
4). Use English on your site.
5). Provide a link to my site in return - it's only fair :)
