Here are some of the sites seriously worth a visit if you have a GPRS/Edge/3G enabled phone.

1. Twitter

Being a huge twitter addict the first thing I checked was the Twitter mobile site.  The site is pretty good and very addictive. Mobile Web is the top source of my tweets now . There are also many other sites through which you can tweet via mobile now.

2. Facebook Mobile

It is a complete striped out version of the Facebook but you can still see your news feed, friend requests, event invitations, update your status and almost everything that you can on the desktop site (Exception being Facebook Chat).

3. Delicious Bookmarks

Here you can browse your Delicious bookmarks, tags, and your inbox. You can also browse the currently popular and recent bookmarks of the Delicious network.

4. Google

It is a one stop shop for all your Google products like Gmail, Google Reader, Google Maps, iGoogle, Blogger etc. Though all of the above have their own dedicated mobile sites. I somehow prefer this site over the others. The only thing missing in this site is Google Talk which doesn’t have a dedicated mobile site as well.

5. Flickr

Flickr recently revamped their mobile site after they saw that lots of people are using their mobile devices to click and upload pictures on the go. Now you can also comment and favorite photos from your mobile. iPhone and Google G1 users can also get to watch videos of upto 90 seconds on their phones.

6. NDTV / CNN IBN / The Times of India

Realising the potential of mobile internet users, many news agencies have now started  dedicated mobile sites for people to read the top stories on the go.

7. Brightkite

I use Brightkite quite often. So I was also interested to know how its mobile site is and I was quite surprised to see that Brightkite mobile site has a lot of features. You can check in at a place, post notes and photos, see the people near you, check your messages etc etc. In short, it provides all the features that the main site provides in a striped down version.

8. m.ebuddy.com

This site is like a heaven for all the chatting addicts. This site currently supports MSN, AIM, Yahoo Messenger, ICQ, Google Talk, My Space and Facebook Chat.

9. Cricinfo MobiCast

We all are cricket fans. Isn’t it?

Understanding this, Cricinfo has a dedicated MobiCast on which they list the scorecards of all the live matches happening right now along with ball by ball Commentary.

10. Zapak Games

If you are a gaming addict and love Zapak’s games, then you would simply love the Zapak’s mobile site. Here you can play single player and multi player games, download games from a list of around 900+ games etc.
