TweetCaster failed to log into twitter. This is a problem that often arises when using the phone or tablet TweetCaster android. I often come across this problem. Some people think this is the internet connection problem, because some providers have to be set manually. But this is not the Internet connection problems. Even when you get the EDGE network, you can still log into twitter TweetCaster. Here’s the way that you do not fail
It is a matter of time setting date. Uncheck the automatic time updates from the provider. Then set the time according to your location (time zone), do not forget to set your date. Everything must be completely up to date. If all the above settings are correct, you can log into twitter with any application. I’ve tried these tips.

I am using TweetCaster Pro 5.6. You can use your favorite twitter program
