I maintain and develop on the Windows Mobile platform.
I know the market is changing rapidly with iPhone and Android gaining market shares.
There are also app development platforms like rhomobile/titanium.
Are there any platform/non platform specific mobile conferences this year?
What would be some of the important/useful conferences to attend in the mobile arena?
Thanks in advance.
Google I/O is supposed to have a lot of Android content this year, and the videos from last year are pretty useful. Unfortunately I think its too late to register.
For the iPhone, you'd want to go to Apple's WWDC conference. It hasn't been officially announced for this year, but many sources point to June 28th as its start date.
I personally don't know anything about this camp, but someone else asked about the Big Nerd Android Bootcamp in this other question. The courses were written and are taught by a very active member of the Android community here on Stack Overflow, so at least you know he knows his stuff!
Depending on your city, there may be a local meetup of iPhone and/or Android developers. These are typically free or cost a few dollars to attend, so I think they are a great place to start. Check out meetup.com for more.
