Hi String,
Case #1: Maxis
Case #2: Sorry if i understand wrongly "The physical contact inside the jack needs to be cleaned." does this mean i can use cotton, stuck it inside and clean it? I'll try this tonite. But any other reason causing this? I am SO SO worry that it's spoiltÂ

It may be the case of your carrier, not your iPhone, that error during sending your SMSes. While roaming in Frankfurt, the carrier was changing between the T-Mobile and SFD while I was there, and this happened while I was sending a couple of SMSes back home. The same error you described happened to me. Resending the SMS after I was in a constant stable coverage area, eliminates this error. This may be the fault of Maxis, not your iPhone.
As for case #2, DO NOT shove cotton buds into your headphone port! That will make it worse, strands of those cotton lint may get stuck to the contacts inside the iPhone. Try reinserting and pulling out the cable, and see if that helps. Also, do you do dock your iPhone in anything else OTHER than its own supplied dock? I am currently using a Universal Dock because the crystal case I'm using does not fit the original dock, and before the recent firmware update, I have had cases where the call ringtones were muted, and answered calls immediately goes into voicemail when iPhone is pulled out of the dock. I have yet to experience anything like that after the new update. If you do dock it with anything else other than its supplied dock, try not to. Use its own supplied USB cable.
Other than that, I hope anyone else who had similar predicament as the TS can come forward with their possibe solution.
