Well I was in a pub with some friends, the phones were on the table, and one friend received an SMS text from a common friend, and after about 2-3 seconds I got the sms too. I was no mass sms text because it was dedicated to that friend of mine. I read the sms and asked that guy, is this the sms you just received? And he was... HOW, HOW DID YOU GET THAT? Events like that happen that night, I even got sms messages that were not in my agenda, and when I asked those friends they were all very "WOW" about this problem. I didn't get sms from only one device, I got sms'es from device in a range of about 2-5 meters, if I would sit next to them, I would get their sms'es on my phone.

It was weird because we tried to recreate the conditions that got to this weirdness but couldn't. After 2 years I opened up the build archive again and tried to recreate the same conditions on my Samsung GT I-9000 but no succes, the "problem" never came up...

P.S. worked only on other Android devices, if the person next to me had a windows mobile smartphone, or a phone with proprietary os it wouldn't work... It wouldn't matter what Android version they had, it just had to be Android, my version was 4.0.4 beta based on CyanogenMod port.
