There are couple of blogs which I found useful and have been started this year.
3GPP Wireless Technology Demystified
This is by my colleague Venu Panchamukhi and its a very technical blog covering HSPA, HSPA+ (Release 7) and hopefully HSPA Evolution (Release 8) soon.
Wired n Wireless
This is another technical blog with focus on LTE with a mix of some other news.
If you are a new blogger and would like everyone to know about your blog then please feel free to add your blog in the comments. No Spam please as I am going to check each of the links before approving it. Also note that the blog should be related to telecoms, wireless, 3G, 4G, etc.
