Much better

The Blunt PPP speed problem was indeed caused by the wrong MTU settings. While trying to fix a problem when sending data via OBEX, I saw that the code for correct data segmentation during sending was still missing. The workaround at the moment is to use a small MTU size which will fit into the HCI buffer to the card and maybe add segmentation later. PPP over GPRS works fine now… the Newton is not a speed daemon, but it is definitely enough for browsing the web with Courier. And there is still the option to add gzip compression to NHttpLib.
