I have the LG Optimus U through US Cellular, had it since January. The messaging is starting to act up. It's VERY slow at sending, and a lot of times I get an alert that the message didn't send. I have the inbox set low, 200 texts and 50 picture messages, I don't have a lot of apps on my phone, and I just had a software update in April. What is wrong with my frickin phone?! Ah thanks for your help!!
