Anyone experiencing receiving blank sms (just the bubble) from "unknown" issue after their jailbreak? I have only started receiving them these 2 days after the jailbreak. I have been trying to trace down if it is a sms from a known friend or spam or perhaps organisation like banks/telco as I do receive updates from them once in a while. This is getting me worried that I might be missing some important sms. I tried installing Message+ as some people adviced but it still made no difference.
