I have a 30pin dock clock radio I used with my 3GS with corresponding dock adapter. I just upgraded to a 4 (I know, I know- in the past right?). However, I am insistent on keeping my iPhone 4 in a case. As a consequence, it will not fit into the dock with a dock adapter.
Is the adapter essential? I haven't bothered using on with my iPod touch as it is light, but the iPhone is heavier. It stays upright and I imagine it would be okay, but do you think it would damage the phones dock over time? Has any one had any experience of this occurring, or have you used docks like this with no problems?
